Application flied April 13, 1915. Serial No. 21,165.

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanical Sheet-Controlling Means, of which the following is a specification.

This invention relates to certain new and useful improvements in mechanical means for controlling a traveling sheet or Web,

for instance, as is employed in automatic musical instruments. It has for its Objects among others to provide a simple and efficient web or sheet controlling means, purely mechanical, without the employment of pneumatics or analogous devices and which shall be affected, as are pneumatic devices of this nature, by leakage of air or by stoppage of openings by lint or other extraneous matter. My present construction, furthermore, is easily adjusted, practically frictionless, be ing most sensitive in its movement, requiring but little pressure of the paper upon the edge guides to cause movement of the transmission mechanism.

I provide mechanically for the use of sheets of different widths without alfecting the operation of the other mechanism by the introduction of the sheet of whatever width.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and inwhich Figure l is a front elevation with portions broken away, showing the application of my present improvement.

Fig. 2 is a. top plan.

Fig. 3 is a perspective view with portions roken away, showing my present improvement removed from the instrument.

My present improvement in a mechanical sheet controlling device the employment of pneumatics and wish it so considered. The other elements of a mechanical musical instrument ierein shown and hereinafter referred to are herein disclosed merely for the purpose of illustration and showing the ap piication of my present improvements, it being understood that the invention thus broadly stated is in no wise restricted to any particular construction. of the eiements of the instrument other than as hereinafter specified.

The music box 1, the take-upspool 2, tracker-bar 3, the music spool 4;, its spindles 5 and the re vind mechanism 6, as well as the sprocket chain 7 and sprocket wheel 8, are of any well known or approved form, the latter being mounted u on the shaft 9, which, as will he hereina ter described, constitutes a part of the transmission device which comprises the two U-shaped membore 10 and 11 fixedly secured together and having the depending portions 12 and 13 respectively at their opposite ends and in which depending portions at one end the shaft 9 is mounted, as seen in Fig. 1. A suitable brace, as shown at 14, may be employed, if n cessary, to hold the depending portions 12 and 13 in their spaced relation. The members 10 and 11 may be made of aluminum or other suitable material combining strength and lightness and they are supported upon the uprights 15 which at their upper ends carry the pins or the like 16 which are mounted loosely in the adjacent portions of the innermost U-shaped bar, as seen clearly in Fig. 1'. The lower ends ofthese uprights 15 are mounted upon screws or the like l7 held in the ends of the music box, washers or the like 18 being provided between the said uprights and ends, as seen in Fig. 1. These uprights are free to oscillate within certain limits in the direction of the'length of the music box.

Extending from one end of the music spool resides broadly- Elll of this segment is toothed, as see box is a bar or i9 nllixed thereto in any suit-able manner and in this her is pivctuliy mounted, as at 20, the oscillating HH JJQlJEI the upper end of which in this instance shown as bifurcated, as shown at which bifurcation loosely receives a 23 tending laterally from the llOllZOlltfilEI-QI: tion of the shaped member 10, shown clearly in s. 1 and 3. The lower end of this oscillating member 21 is in. I )rm of a segment, on the of a circle 0' which the pivot 20 is the center. The .teoe

end meshes with at toothed Wheel 1? by a shaft. 27 mounted one end i n. 28 secured to the of the music box. i its other end, carries a friction wheel. c periphery of which. is preferably milled or roughened, as seen at 80 seen in 2, or it maybe smooth, as seen in This end of the shaft is journc. ed in an arm 31 which is fixedly secured, as art 32, to one end of a swinging suspended curring c 33, seen hes-t in Fig. 3, in which letter view the parts constituting my present invention are shown in perspective separated ion). the machine prooer but with the ports in their relative positions. This cur-r1 Qe suspended by the bails or hangers one each end, the cross portions of the hails loeim mounted for free movement in the mom ers 36 which are attached to the inner faces of the ends of the music spool box, as seen in Fig. 1, and their lower ends are preferably connected with the carriage 33, as seen in Fig. 2' wherein the members are shown as screw threaded st 37 and pass through openings in the carriage 33, being provided upon their lower ends with. nuts or the like 38, preferably seated in sockets 39 in the under face oi the carriage and buttons or the like $0 provided upon the upper face of the carriage and seated thereupon. .lhis provides for the necessary aidjustment, as well as ready assemblage of the parts or removal thereof for repairs or other purposes when desired.

Pivotally mounted on the upper face of the carriage 83, as ate are the preferably fiat oars l2 which, in'the present instance, are shown as twisted near their outer ends, as at %3, to form the substantially vertical .members is which serve es edge guides to contact with the opposite edges of the note sheet 45. The terminals of th edge guides are outwardly inclined. or rounded as seen at 4-6 in Figs. 2 and 3, so as no resistance to the insertion of the music sheet so as to avoid any tendency injure the latter. Springs 4?, as seen in 2 and 3, are provided, bearing against these bars $2 near their" pivots, tending to nor molly hold thehars inward toward eech other and substantially parsllel with each other. They are sufliciently delicate to pen nziy loe eccoinplislied and attention ca thrown into position for rewind, and th's essons ment of the the edges of the music s burs are con iniison by pistes cuter ends to the bars .s

Fig. 3, when said member 51 is moved outward. in placing the inec in condition. rewind, the said arm 22 is pulled outward end, consequently, other sun is moved in the opposite direction so that all liability of in jury to the edges of the sheet as the latter ice is rewound upon the music spool is obviated. The friction wheel disposed. between two disks 53 and ill, the adjacent feces of which are preferably tar-cc. with rubber or analogous material, us seen best in lfig. ll. These disks 53 and 5%. BIG carried by t'll" sleeve 56 loosely mounted on shaft 5 supported at one end in the adjacent end of the box 1 and at the other end in on up right 58 extending from an arm 53) secured. ile

to the adjacent cud of the box .1, cs in Fig. 1. The diameter of the friction roller 29 is but slightly less than the space between the adjacent faces of the two disks 5-25 and 5%, as seen in i, so that while there room for some play of this roller he col! the disks, this play is very slight, in practice possibly not more than two one-tliousondths of an inch.

The sleeve 5e carries as seen in l l "0 n inent suitable means, such as collars secured the shaft l2; screws or Ls'lB as is also in Fig. 6. Motion is imparted to the sprocket 60 and, consequently, to the disks 5 5 by moons of o. sprocket chain 6smessed around sprocket wheel 60 and a sprocket wheel 65 on the shaft 66 of the take-up spool.

The wheel 65 is held against movement lengthwise of the s 66 by suitable means, as a collar 67, ad to said shaft, as seen in Fig. 1. c the hub of the sprocket wheel 65, periphery being toothed to constitute a ratchet, seen clearly in Figs 1 and 4;. This is loosely mounted upon the shaft 66 and is caused to turn therewith-in one direction by means of a dog or pawl 69 pivotally mounted on the face of the 'huband engaging a toothed collar 7 O fixedly secured to the shaft in any suitable manner. 71 is a dog or pawl pivotally mounted, as at 72,. upon the under side of the member 59, see Figs. 1 and 4, and adapted to engage the teeth of the ratchet wheel 68 to prevent retrograde movement thereof, but permitting of its turning freely in the other direction.

During the operation of playing, the sprocket wheel revolves with the shaft 66 and through the medium of the sprocket chain 64 and sprocket wheel 65, the disks 53 and 54 are continuously revolving. On the rewind, however, it is desirable to have the guides moved outward away from the edges of the note sheet and to throw the friction wheel 29 out of operation so as to hold the music spool from endwise movement. -Con sequently, when the member 6 is moved to the right for rewind, the edge guides are moved simultaneously outward through the connections 51 and 52 hereinbefore described and the ratchet wheel 68 is held against rotation with the shaft 66 throu h the medium of the dog 71 engaging t e teeth of the ratchet, as seen in Fig. 4, and the pawl 69 engaging the teeth 70.

With the parts constructed and arranged substantially as hereinbefore described and with such parts in the position in which they are shown in Fig. 1, ready for playing, the operation is as follows:

Normally, when there is no music sheet in the instrument, the edge guides 44. are pressed inward to their greatest extent so that the distance between them is less than the width of the narrowest sheet. When the sheet is introduced, the outturned terminals 46 of these edge guides permit of its ready insertion and the pressure of the edges of the sheet upon the inner faces of these edge guides overcomes the pressure of the springs 47, so that the edge guides are moved outward'or away from each other.

to accommodate the sheet/no matter what width it may be. ,If the sheet when introduced is not central, the pressur one edge of the note sheet against its guide will be greater than that of the other edge which causes the carriage 33 and the parts movable therewith to move in the direction of the greater pressure and this into contact with the corresponding disk 53 or 54 which, in turn, causes the toothed wheel 26 to revolve in one direction or the other and by reason of its engagement with the toothed segment 2 1. moves the latter on its pivot, and such movement through the connection 22 and 23 with the transmission mechanism-10, 11, etc.which moves the music spool in the proper direction to ccntralize the sheet. the playing, the least deviation of the note sheet to the right or left will throw'the friction wheel 29 out of contact with the one disk and into contact with the other, or vice versa and thus through the medium of the toothed segment and the connections above described keep the sheet centralized throughoutthe playing of the piece.

Upon the rewind the friction wheel 29, the disks 53, 54, the toothed segment, etc, are idle and perform no function.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

By transmission mechanism or transmission device, I mean the members 10-11, the back and forth movement of which transmits motion to the music spool 4, movin it to the right or left.
